WEESSNordsee
Containerised energy storage system on a utility-scale. The Nordsee 4472 combines 4,472 kWh of capacity with prefabricated container architecture for load shifting, peak shaving, frequency control, arbitrage and the integration of renewable energy.
WEESS Nordsee acts as a large-scale containerised energy storage solution within the energy system. The system combines battery technology, power electronics, liquid cooling and energy management within a robust, prefabricated containerised architecture.
The Nordsee transforms storage capacity into grid- and market-ready infrastructure.
It is not just the size of the system that matters, but the question of what tasks the storage facility can actually perform within the project.
Frequency and voltage
The Nordsee is designed for grid-related applications and can support frequency and voltage control for grid operators and infrastructure projects.
The Nordsee is designed for applications in which grid quality and control speed play a central role.
The system can shift electricity over time in such a way that price differences are exploited operationally.
The Nordsee buffers generation peaks and helps to balance out volatile feed-in profiles.
The system is designed for project scales where multiple storage facilities, higher capacities and larger infrastructure networks become relevant.

Where the Nordsee is particularly well suited
The Nordsee is intended for projects in which large storage capacity is to be combined with grid logic, generation integration or multi-MW flexibility.
Transmission networks
When primary and secondary control power are relevant for TSOs and fast response times are required for grid stability.
Wind farms and solar power plants
When generation peaks need to be buffered and fluctuations in the feed-in profile need to be better balanced.
Industrial parks
When large C&I sites require advanced load management, optimisation of self-consumption and robust storage infrastructure.
Grid Services & Control
Smart grid services for maximum returns.
Example scenario
Frequency control · Grid services
Network services
System status: Frequency deviation detected (49.98 Hz). Nordsee responds by feeding in +450 kW within 45 ms to stabilise the grid.
When the Nordsee is particularly well suited
The Nordsee is the right choice when a large-scale storage facility needs to do more than simply provide capacity.
Network operators & utilities
- When frequency and voltage control, pre-qualification for control power and multi-MW projects are the main focus.
Renewable energy project developer
- When wind and solar farms need to be better integrated, generation optimised and grid connection solutions designed with greater flexibility in mind.
Large industrial consumers
- When multi-MW peak shaving, self-consumption optimisation and backup are relevant for critical processes.
Utility-scale storage for your projects
WEESS Nordsee 4472 is the choice for multi-MW projects involving grid services, arbitrage and renewable energy integration.
